RAISING MECHANISM FOR CENTER-DRAFT-LAMP WICKS..

SPECIFICATION forming part of Letters Patent No. 588,140, dated August 17, 1897. Application filed October l5, 1896. Serial No. 608,934. No model.)

To all whom, it' may cor/acer Be it known that I, WILLIAM H. GINDEE, Y a citizenof the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented a certain new and useful Improvement in Raising Mech.- anism for Center-Draft -Lamp' Wicks, of which the following is a specification.

My invention relates to a new and useful improvement in wick-raisers forcenter-draft lamps, and has for its object to provide such a device by means of which a circular wick may be raised or lowered upon a stationary wick'- tube without being permanently attached to any part of the mechanism and also to permit the ready insertion of a wick within a lamp around the wick-tube or the withdrawal thereof from said tube without in any way altering or disturbing the raising mechanism.

A further object of this invention is to greatly cheapen such mechanism and render it more durablethan has heretofore been the case.

Vith these ends in view this invention consists in the details of construction and coinbination of elements hereinafter set forth, and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, its construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a central section of the reservoir of a lamp, showing the wick, wick-tube, and raising mechanism in elevation; Fig. 2, a section at the line rco: of Fig. 1, looking in the direction of the arrow 5 and Fig. 3,a section of a portion of the lamp, looking in the direction of the arrow in Fig. 2.

In carrying out my invention no alteration is made in the reservoir A or the wick-tube `B, the latter being adapted to receive the wick C, which is passed thereover without being in any wise attached thereto in order that it may be free to move up and down in 5o raising and lowering the flame supported upon its upper end.

Brackets D and E depend from the under side of the cap F and have journaled therein the shafts G, upon which latter are secured the star-wheels H. These shafts are set at an angle to each other, so that the star-wheels are brought into close proximity to the wicktube upn either side thereof, thus forming four points of contact with the wick when placed around said tube, whereby when the 6o starwheels are revolved the wick will be raised or lowered by the engagement of the teeth of the star-wheels therewith.

Just inside of the brackets D are secured upon the shafts the gear-Wheels I, of such a diameter as to mesh together, as clearly shown in Fig. 3, and this arrangement will cause the two shafts to revolve in unison, and the revolving thereof is accomplished by the pinion J, meshing with one of the gear- 7o wheels I. This pinion is secured upon the inner end of thebperating-shaft K, which latter is journaled within a suitable tube L, secured within the cap', and for convenience in manipulating the shaft K a knurled button M is secured upon the outer end thereof.

From this description it will be obvious that to place awick in proper position Within the lamp it is only necessary to pass the same over the wick-tube and force it downward un- 8o til it comes 'into engagement with the starwheels H, when by revolving said st-ar-wheels, as before described, in the proper direction the downward movement of the wick will be continued to the desired point. After this has been accomplished it is obvious that the raising and lowering of the Wick for the usual purposes may be quickly and readily accomplished by the tu rning of the button M. Should it any time become necessary to re- 9o move the wick from the lamp, the star-wheels are revolved until the wick has been forced ont of action therewith, after which it may be withdrawn by lifting it from the tube.

The disadvantages which have heretofore been experienced in the manipulation ofwicks in center-draft lamps, and especially the rewicking of such lamps, are entirely overcome by my improvement, since the Wick is not permanently attached to any part of the lamp roo or raising mechanism and may be carried into and out of engagement with the star-wheels by the simple operation of said wheels through lthe knurled button, whereas in the ordinary lamps of this description it has been necessary to secure the wick by stitching or wiring to a secondary tube, which entered into engagement with some portion of the mechanism and required considerable experience for its proper adjustment.

One of the marketable advantages of my improvement is that the Wick is raised or lowered by the revolving of a button in easy access of the hand, and said button is operated in all respects in the same manner as the wickraising button of an ordinary flat-tube burner.

The cost of manufacture of my improvement is small, since all the parts thereof are made by automatic machinery and require no adjustment and when assembled are not likely to become disarranged or worn, since it is not required that they should fit accurately,which would cause wear.

Having thus fully described my invention, what I claim as new and useful isl. In combination with the wick-tube of a center-draft lamp, shafts journaled in the reservoir on opposite sides of the tube and at an angle to each other, two star-Wheels mounted on each shaft, gear-Wheels also mounted on the shaft and meshing with each other, a pinion meshing with one of the gears, a shaft upon which the pinion is mounted, said shaft extending to the outside of the reservoir, as and for the purpose described.

2. The herein -described combination of the brackets secured to the casing of the reservoir, two oblique shafts journaled within said brackets, two star-wheels carried by each of said shafts and arranged to revolve in proximity to the wick-tube and in engagement with a Wick when upon said tube, a gearwheel secured upon each of the shafts and meshing together so as to cause the shafts to revolve in unison, a pinion meshing with one of the gear-wheels whereby motion is imparted to the latter, a shaft upon which said pinion is secured, a tube projecting through the casing of the reservoir and in which the lastnamed shaft is journaled, and a button secured upon the outer end of said shaft, substantially as and for the purpose set forth.

In testimony whereof I have hereunto nfiXed my signature in the presence of two subscribing witnesses.
